Singer Aaron Carter has been arrested less than a month after being hospitalized in Syracuse for “health issues.”

The 29-year-old pop star was pulled over by Habersham County sheriffs in Georgia Saturday night, TMZ reports. He refused to submit to a breathalyzer or blood and urine testing for driving under the influence, and was charged on suspicion of DUI, possession of marijuana, and possession of drug-related objects.

According to the celebrity gossip site, Carter’s girlfriend Madison Parker, who was also in the car, has also been arrested.

Hours before his arrest, Carter told fans on Twitter he would be unable to make a concert in Kansas City due to “transportation issues.”

The incident follows a dramatic episode four weeks ago where he checked himself into the emergency room at St. Joseph’s Hospital in Syracuse, hinting he needed treatment for exhaustion. Carter posted photos of himself smiling in a hospital bed and wheelchair for “a little check up” after performing “lots of shows lately.”

Carter, the younger brother of Backstreet Boys singer Nick Carter, later said on Twitter that he had been bullied and “body shamed” earlier that evening at a HOT 107.9 concert in Liverpool.
